These studies clearly demonstrate that polymer-based PnCs constitute an attractive material platform for the development of high-frequency sonic devices, given by the multitude of suitable fabrication techniques of polymers, such as self-assembly, spin-casting, IL, etc. (see Section 2), which can be utilized for creating a wide range of 1D, 2D, and 3D periodic sub-micrometer structures.
The brains were quickly removed, the cortex were dissected on ice and homogenized by sonication at high frequency (70 Hz) for 4 s using a VibraCell Sonicator (Sonics and Materials, Newtwon, CT, USA) in ice-cold perchloric acid (0.1 mol/l) containing 1 g/l cysteine.
Also, the data indicate that, following the exposure to the sonic booms, the high frequency hearing is influenced first.
Even on my small yacht I had a depth gauge which worked with pulses of high frequency sound, the Titanic was located with scanning sonar, and there was, and may still be, a chain of sonic detectors in the North Atlantic to detect submarines.
This includes machine design and construction, sonic frequency, sonic power, proper and compatible cleaning chemistry, whether aqueous or solvent.
